smbios: Allow a few values to come from sysinfo
While static configuration is useful it cannot cover every case. Sometimes board revisions are encoded in resistor straps and must be read at runtime. The easiest way to provide this information is via sysinfo, since the board can then provide a driver to read whatever is needed. Add some standard sysinfo options for this, and use them to obtain the required information. Signed-off-by: Simon Glass <sjg@chromium.org> Reviewed-by: Bin Meng <bmeng.cn@gmail.com>
